The GE DS200RTBAG1AHC is not a PLC,but a relay terminal board from the General Electric(GE)Mark V series.It is primarily used for relay signal transfer,distribution,and protection in industrial turbine control systems.It serves as a key interface component between control modules and field actuators.The following are its details:
I.Basic Information and Positioning
Brand:GE
Series:Mark V Speedtronic(designed for control systems for large rotating equipment such as gas turbines and steam turbines)
Function Type:Relay Terminal Board(RTB)
Core Function:Serves as an intermediate interface between the control module and external actuators such as relays and contactors,providing physical signal transfer,electrical isolation,and line protection to ensure reliable transmission of control commands.
II.Core Functions and Technical Features
Signal Transfer and Distribution
Equipped with multiple terminal blocks(typically two main terminal blocks),it supports centralized wiring of multiple relay output signals.It can connect field devices such as contactors,solenoid valves,and indicator lights,simplifying control system wiring.Digital output modules compatible with the Mark V system(such as the DS200DTBC series)convert low-level logic signals from the control module into high-power signals capable of driving external loads.
Electrical Isolation and Protection
Built-in isolation circuitry provides electrical isolation between the control side(low voltage)and the load side(high voltage)(typically≥1500V AC),effectively eliminating ground loop interference and surges,protecting the core control module.
Some terminals are equipped with overcurrent protection elements(such as fuses or current-limiting resistors)to prevent module damage caused by external load short circuits.
Industrial-Grade Reliability Design
Operating temperature range:-40°C to+70°C,suitable for harsh environments with high temperatures and vibration,such as turbine rooms.
Mechanical Construction:Utilizing a robust PCB design,it supports DIN rail or rack mounting,and features anti-loosening terminals for long-term stability.
Status Indication:Select versions feature LED indicators that visually display power on/off and signal status,facilitating quick troubleshooting.III.Technical Parameter Overview
Item:Typical Specifications(See official documentation)
Number of Terminals:Typically supports 30-50 signal connections(specific specifications vary by model)
Rated Voltage:Compatible with industrial voltages such as 24V DC,110V AC,and 220V AC
Maximum Load Current:Typically supports 1-5A per relay output(depending on load type)
Isolation Strength:Control-side to load-side isolation≥1500V AC(1 minute)
